Hi,
I executed 'color zone #2 near #1 distance 5 sharpEdges true' to colour a map I loaded, followed by "volume splitbyzone #2', but repeatedly would get an error that the volume specified is not coloured by zone. Eventually after trying multiple times, it worked, however the log outputted the following:

I also get the following when using the color zone command, even though color zone works (most of the times, sometimes it fails)
